Appl. No.:

11/334979

Inventors:

Raymond Keith Foster - Madras OR, US
Daniel W. Jackson - Redmond OR, US
Brian Lance Salyer - Bend OR, US

International Classification:

B65G 25/04

US Classification:

1987502, 1987501, 1987503, 1987504, 4145251, 4145259

Abstract:

An elongated plastic slide bearing () comprises a top (), sidewalls () depending from the top (), and connecting to walls ( and ) that form laterally inwardly extending recesses (). Lock ribs () extend upwardly and inwardly from the inner walls () of the recesses () to upper edges (). The upper edges () are spaced below the bearing top (). The bearing () is adapted to be set down onto a support beam () that includes laterally outwardly projecting lock flanges () at its top. The lock ribs () contact the lock flanges (). When the bearing () is pushed downwardly, the lock ribs () bend outwardly and allow the lock ribs () to move into a position below the lock flanges (). When that happens, the lock ribs () assume substantially unstressed positions in which their upper edges () are below the lock flanges (). The sidewalls () and the lock ribs () are bendable to allow a floor slat () to be snap-fit down onto the bearing ().

Assignee:

Keith Manufacturing Co. - Madras OR

International Classification:

B65G 25/06
B65G 25/04

US Classification:

1987503, 1987502

Abstract:

Movable conveyor slats () have side parts () which rest on top parts of bearings (). The bearings () have a generally U-shaped cross section and they fit on wings (′) which extend outwardly and slope upwardly from the sides of a fixed conveyor slat (′). Fixed conveyor slats (′) have base portions (′) and upper insert portions (′). The inserts (′) have downwardly extending ribs () on their sides which extend into upwardly opening grooves () in the base portions (). The movable slats () have web () and lower flange portions () which with the side parts () of the slats () form laterally outwardly opening channels. The wings (′) and the bearings () are received within the channels ().

International Classification:

B60P 1/00

US Classification:

4145251, 414527

Abstract:

A sheet member () is positioned on the slats () of a reciprocating slat conveyor in a container (). A strap () leads from the forward end of the sheet member () to and through a guide eye () that is mounted at an elevated position () adjacent the front wall () of the container (). The strap extends downwardly from the guide eye () to a winding reel () driven by a motor (). A block () is connected to the strap () in a position so that when the front end of the sheet member () has been moved by the strap () into an elevated position adjacent the front wall (), the block () on the strap () will move through the throat () of the guide eye () to the opposite side of a latch spring () that defines one side of the throat (). When in this position, the block () contacts the latch spring () and is hard against a reverse movement of the strap () and block () through the guide eye (). However, when the conveyor is operated to move material (M) out from the container (), it will impose a sufficient amount of force on the sheet member () to cause a pulling force on the strap () sufficient to move the block () back through the throat () of the guide eye (), against the force of the latch spring ().

James P. Drago - Metoluis OR, US

International Classification:

B65G 25/04

US Classification:

1987502

Abstract:

Conveyor slats (″) are supported for longitudinal movement along support beams (′). The slats (″) are constructed from a structural plastic material and the support beams (′) are constructed from metal. The support beams (′) have a center portion in the form of an upwardly opening channel formed by side walls (′ and ′) and a bottom wall (′). A top is formed by side parts (′ and ′). Side parts (′) project laterally outwardly from the upper edges of the side walls (′). A top side part (′) projects laterally outwardly from the upper edges of the side walls (′). The conveyor slats (″) have a top wall (″), a pair of side walls (″ and ″). Inwardly projecting flanges (″ and ″) project laterally inwardly from the side walls (″ and ″). Outer side edges on the support beams (′) are positioned to contact shoulders on the flanges (″ and ″) to prevent unwanted upward movement of the slats (″) off from the beams (′).

Inventors:

Daniel W. Jackson - Madras OR, US

International Classification:

B60P 1/00

US Classification:

414509

Abstract:

An improved outer reciprocating floor slat for use in a truck trailer or the like. The outer floor slat is located adjacent to a trailer's side wall. The floor slat has a portion that extends laterally upwardly and outwardly until it reaches the trailer's side wall at an elevation above the normal load-carrying floor elevation of the reciprocating floor slats. The upwardly extending portion facilitates material movement away from the corner region where the reciprocating floor normally intersects the trailer's side walls.

Abstract:

A method for producing a power field effect transistor (FET) device having a low series resistance between the drain and source when switched on has the steps of: forming a vertical power FET in a semiconductor die; and back-grinding the semiconductor die to a thickness of less than or equal to about 100 μm (4 mils) or less.
